4.2.4 Load Search and Rescue Pattern (Optional)
NOTE: This optional feature is available in software version 6.00 and later.
NOTE: Turn smoothing may result in SAR coverage being different than
intended. The flight crew should always verify that the SAR pattern created
conforms to the specific mission requirements.
Search and Rescue Patterns may be added to existing waypoints within
the active flight plan. Only one SAR pattern can exist in the active flight plan.
Loading another SAR pattern into the active flight plan when one already exists
will remove the first SAR pattern.
Each pattern has a default initial track. When the pilot changes the initial
track on a SAR pattern, that change becomes the default initial track the next
time the SAR pattern is accessed within the GTN. The pilot can always change
the initial track when creating a SAR pattern in the flight plan.
NOTE: Flight plans cannot be stored in the catalog if they contain a SAR
pattern.
1. On the Active Flight Plan page, touch the desired waypoint in
the flight plan. The Waypoint Options list will then be displayed.

6.13 Points to Remember for All Procedures
• The GTN 6XX Map page is designed to complement your printed approach
plates and vastly improve situational awareness throughout the approach.
However, you must always fly an approach as it appears on the approach plate.
• The active leg (or the portion of the approach currently in use) is depicted
in magenta on the Map Page. As you fly the approach, the GTN 6XX
automatically sequences through each leg of the approach unless “SUSP”
appears at the annunciation bar at the bottom of the display. “SUSP”
indicates that automatic sequencing of approach waypoints is suspended on
the current leg and normally appears at holding patterns and upon crossing
the missed approach point (MAP), for Climb to Altitude legs, and for Hold
to Altitude legs.
•
For roll steering autopilots: roll steering is terminated when approach mode
is selected on the autopilot and is available once the missed approach is
initiated.
• If Vectors-to-Final is activated while on the “FROM” side of the FAF, automatic
waypoint sequencing is suspended and the SUSP annunciation will appear.
Automatic waypoint sequencing will resume once the aircraft is on the “TO”
side of the FAF and within full-scale deflection.
• For all procedures, make sure to check the runway, transition, and all
waypoints.
• Most legs are
“TO”
legs on which the TO/FROM flag on the CDI indicates
“TO”
and the Distance field on the flight plan decreases as you navigate
along the leg. However, some procedures include legs which are
“FROM”
legs. On these legs, the TO/FROM flag on the CDI indicates
“FROM”
and the
Distance field on the flight plan increases as you navigate the leg.
“FROM”
legs are typically found on procedure turns and on some missed approach
procedures.
CAUTION: Not all autopilots will follow guidance when on a heading leg
using NAV, GPSS, or APR mode on the autopilot. Heading legs for procedures
can be identified by “HDG XXX°” in white on the Flight Plan page, as well
as the procedure chart indicating that the aircraft must fly a particular
heading. Certain autopilots will revert to a “Roll Only” or “Wings Level”
mode on these leg types and the pilot must engage the heading (HDG)
mode of the autopilot and set the heading bug appropriately in order to
use the autopilot on these legs.

9.3 Traffic Information Service (TIS) (Optional)
WARNING: The Traffic Information Service (TIS) is intended for advisory
use only. TIS is intended to help the pilot locate traffic visually. It is the
responsibility of the pilot to see and maneuver to avoid traffic.
NOTE: TIS is available only when the aircraft is within the service volume of
a TIS-capable terminal radar site. Aircraft without an operating transponder
are invisible to both Traffic Advisory Systems (TAS) and TIS. Aircraft without
altitude reporting capability are shown without altitude separation data
or climb descent indication.
NOTE: TIS and Traffic Advisory System (TAS) may not both be configured
at the same time.
NOTE: GDL 88 equipped aircraft only: When the radio tower symbol is
crossed out, the aircraft is not a participant in the TIS-B system – i. e. not
visible to other TIS-B clients. The GDL 88 will, however, continue to receive
available TIS-B and FIS-B ground station up-links and continue to display
TIS-B and FIS-B data along with available ADS-B and ADS-R data.
NOTE: Except for GDL 88 or GTX 345 equipped aircraft, TIS, and Traffic
Advisory System (TAS) may not both be displayed at the same time.
NOTE: More information is available about the GDL 88 in the "Garmin
GDL 88 ADS-B Transceiver Pilot’s Guide" and the GTX 345 in the "Garmin
GTX 335/345 Pilot's Guide."
Traffic Information Service (TIS) is designed to help in detection and
avoidance of other aircraft. TIS uses the Mode S transponder for the traffic data
link. TIS receives traffic information from ground stations, and is updated every
five seconds. The GTN 6XX displays up to eight traffic targets within a 7.5 NM
radius, from 3000 feet below to 3500 feet above the requesting aircraft.

9.5.2.7 On Scene Mode
When a GDL 88 (with software version 3.00, or later) or GTX 345 is installed
with a GTN in a helicopter, the GTN provides controls for enabling/disabling
“On Scene” mode. “On Scene” mode decreases traffic alerts when operating near
other helicopters (e.g., news reporting).
1. While viewing the Traffic page, touch the Menu key.
2. Touch the On Scene key to enable/disable On Scene mode.
9.5.3 Rotorcraft Traffic Page Orientation
NOTE: Rotorcraft Traffic Page Orientation functionality is available in
software version 5.12 or later.
When flying at low speeds in a helicopter, heading may not always be closely
aligned with track (it could easily be up to 180 degrees different). If the GTN is
interfaced with a heading source, the ADS-B traffic page will remain fixed with
the ownship heading pointed up. However, if heading is not being received by
the GTN, the display of ADS-B traffic will be unavailable.
When one of the following conditions is true, the ADS-B traffic page will be
unavailable:
• Ownship directionality is invalid (no valid heading or track)
• GPS ground speed is less than 15 knots and ownship heading is not
available
While the traffic display is unavailable due to these conditions, traffic alerts
will be provided in a non-bearing textual form at the top of the traffic page.

9.6 RYAN TCAD 9900BX with the GDL 88
NOTE: When a TCAD is connected to a GTX 345, the available controls
will appear as described for a TCAS in Section 9.5.2.
Ryan TCAD is a system that provides audio and visual alerts for traffic near
your aircraft. The information from this system can be interfaced through the
GTN series. Operating instructions and details on the modes of operation are
described in the Ryan TCAD operator’s handbooks.
• TCAS-like symbols are used in the 9900BX.
• Altitude modes are available (normal, look up, look down, unrestricted).
• Ranges are manually controlled for the current shield.
• Traffic display range selections:
- Ryan 9900BX — 1 NM, 2 NM, 2 and 6 NM, 6 and
12 NM, and 12 and 24 NM.
9.6.1 Ryan TCAD Description
NOTE: Refer to the Ryan TCAD Pilot’s Guide for a detailed description of
the Ryan TCAD System.
The Ryan TCAD (Traffic and Collision Alert Device) is an on-board air traf-
fic display used to identify potential collision threats. TCAD computes rela-
tive altitude and range of threats from nearby Mode C and Mode S-equipped
aircraft. TCAD will not detect aircraft without operating transponders or those
that are beyond radar coverage. TCAD, within defined limits, creates a “shield”
of airspace around the aircraft that detected traffic cannot penetrate without
triggering an alert.
TA: Traffic Advisory. This is traffic with 500 feet, or less, of altitude separation
that is converging or maintaining altitude separation.
PA: Proximity Advisory. This is traffic with 500 feet of altitude separation that
is not a TA.
TRFC: Other traffic.

11.4 FIS-B Weather
The Flight Information Services (FIS-B) function is capable of displaying text
and graphic weather information with GDL 88 and GTX 345 installations. No
subscription for FIS-B services is required.
The FIS-B Function is a graphic weather display capable of displaying
graphical weather information on UAT equipped installations. Graphical data is
overlaid on the map indicating the rainfall detected by ground based radar for a
specific area. The colors indicating increasing levels of rainfall progresses from
light green for light rainfall to magenta for heavy rainfall. Review the Limitations
section in the front of this guide for the limitations that apply to the FIS-B data.
Rainfall data is color coded as follows:
Figure 11-70 FIS-B Weather Precipitation Legend
A cyan checkerboard pattern indicates that no data is available for that area,
and rainfall in that area is unknown.
The FIS-B Function is based on a ground-to-air data link and requires that
the appropriate ground systems are broadcasting weather data and the aircraft is
within reception range of the Ground Broadcast Transceiver (GBT).

15.4.5 Crossfill
Dual units may be interfaced to crossfill information between the two units.
This option will not be available unless dual units are configured.
When Crossfill is turned on with one GTN, it is automatically turned on in the
other GTN. Some items are always crossfilled regardless of the crossfill setting;
others are dependent on the crossfill setting.
The GTN can be can also be interfaced with the GNS 400W/500W units. The
GTN can automatically send the Active Flight Plan and active Direct-To course to
the GNS unit. The GTN User Waypoints can be manually sent to the GNS unit. The
GNS unit can manually send its User Waypoints to the GTN unit. Waypoint names
longer than six characters, or duplicates, sent from the GTN unit to the GNS unit
will replace some characters with a "+" sign, while leaving significant characters to
aid in identification (such as, USR003 becomes US+003).
NOTE: Upon crossfill being activated, the GTNs may take up to 10 seconds
to crossfill the flight plans. The pilot must verify the flight plan in each unit
prior to use.
The GTN and GNS units must have databases with the same cycle.
NOTE: When GPS navigation is lost in either unit, crossfilling may not be
available until GPS is restored in both units. Crossfilling will resume once the
flightplan is changed on one of the units or crossfill is re-enabled.
15.4.5.1 GTN-to-GTN Crossfilling
This data is always crossfilled:
• User waypoints
• Flight plan catalog
• Alerts (traffic pop-up acknowledgement, missed approach waypoint pop-
up acknowledgement, altitude leg pop-up acknowledgement)
• External sensors (transponder status and commands, synchro heading)
• System setup:
- User-defined NAV frequencies to store favorites
- Date/Time convention
- Nearest airport criteria
- Units (Nav angle, Fuel, and Temperature)
- User-defined COM frequencies to store favorites
- CDI Scale setting
- ILS CDI Capture setting

3. After making the desired selections, touch the Back key to
return to the Setup page.
15.7.2 Setting a User-Configured (Manual) Nav Angle
There are three variation (heading) options: Magnetic, True, and User. If
“Magnetic” is selected, all track, course and heading information is corrected
to the magnetic variation computed by the GPS receiver. The “True” setting
references all information to true north. The “User” selection allows the pilot
to enter values between 0º and 179º E or W. When configured by the installer,
there may also be a fourth option: External. If “External” is selected, the GTN
Nav Angle will be synchronized with the on-side MFD.
NOTE: When changing the Nav angle, the DTK on the Flight Plan page
for an approach does not change until that approach is reloaded.
1. While viewing the System page, touch the Units key.
2. Touch the Nav Angle key and then the User key.

Figure 15-64 Bluetooth Setup for Flight Stream 210
15.11.1 Operation
Data output from the GTN and Flight Stream 210 occurs automatically
and requires no pilot action (such as, flight plan, GPS position, and attitude).
Additionally, ADS-B traffic and weather can be output from the Flight Stream
when connected to a GDL 88 or GTX 345 and XM WX and SiriusXM satellite
radio information can output when connected a GDL 69. From the Connext
Setup page, the pilot can enable/disable flight plan importing, change the Flight
Stream Bluetooth name, and manage paired devices.
The device status indicates if the portable device is connected and
communicating with the Flight Stream. The “Auto-Reconnect” setting determines
if the Flight Stream will automatically connect to up to four devices when in
range. When this setting is disabled, the pilot must initiate the connection from
the device. For devices that always reconnect automatically, this setting will not
be shown. Removing a device from this page by pressing “Remove” will require
the device to be paired again before transferring data.
NOTE: If the pairing is removed from either device (portable device or
GTN) it must be removed on the other device before a new pairing to that
same device is established again. Essentially, pairing must be removed on
both devices before repairing.

Paired Devices
Figure 15-67 Connext Setup for GTX 345
From the Connext Setup page, the pilot can enable/disable Bluetooth, change
the Bluetooth name, and manage paired devices. On the Paired Devices page,
the device status indicates if the portable device is paired and connected. To
connect a different device when the maximum number are already connected,
the existing connection must be ended by removing the portable device pairing
or by disconnecting or disabling Bluetooth on the portable device. Removing a
device from this page by pressing “Remove” will require the device to be paired
again before reconnecting.
NOTE: If the pairing is removed from either device (portable device or
installed avionics) it must be removed on the other device before a new
pairing to that same device is established again. Essentially, the pairing
must be removed on both devices before re-pairing.
New devices can only be paired while the unit is in “Pairing Mode.” Pairing
mode is active while on the Connext Setup page or the Manage Paired Devices
page. The pairing must be initiated by the portable device. A pop-up will be
displayed on the portable device to confirm the pairing.
